I don't know the first thing about cars since I can't drive, so the corollary of that is that I know nothing about petrol/gas stations. I didn't know where to begin with these questions, but I did manage to find out those containers that store fuel are called jerrycans. I googled terms like 'makeshift jerrycans' and 'homemade jerrycans' but just found forum threads about jerrycan holders. I did manage to find a forum claiming hydrocarbons in fuel melt Coke bottles; in Australia (where I live), there's actually a fuel container standard, and you can't store it in glass.
- What are fuel dispensers powered by? I did some Googling on this and the Wikipedia page doesn't specify. I also searched things like 'gas pump power supply' with quotes and no quotes and using various synonyms, asked my mom, etc. Can't go to a petrol station since I've fractured my ankle and it's late, so I figured I'd ask here.
- What can you use as makeshift jerrycans (those containers that store litres of petrol), if bottles aren't safe?
- Would the petrol be contaminated by, say, juice or soda residue? (My characters are in an emergency, so they might have to use something unsafe)
